[21][22] On the review of Contra la Corriente, the Newsday editor Richard Torres commented: "Few vocalists can go from a whisper to a scream as beautifully as Anthony.

[23] A writer for the New York Daily News noted that the song "reflects the fusion of R&B and Latin rhythms so characteristic of his music".
